I am modelling some simple buildings in Blender and importing them to Poser 8 as obj files. I wanted to apply some image map textures to them in the material room,  but I am getting really bad results when rendering.

I then tried it out on the primitive square.

Here is a screen capture of the preview of the square with the texture applied.

Here is what I get when I render it with Firefly.

I tried the same thing in Poser Pro. I also get black marks when rendering with Firefly in Poser Pro, but with the Poser 4 renderer it renders fine.

I updated my video card driver, no effect. I am using an NVidia GeForce 9500 GT with 2 GB of Video Ram. Quadcore machine running Vista Business 32 Bit, 4GB of RAM installed.

Everything else renders without any problem. I seem to get this with flat surfaces with image map textures applied, where the object is not UV-Mapped.

Is this a known problem that I am just encountering now?

 It's an old problem that has (perhaps) been worse after SR1. I't sbeen a while since I've seen people complaining about it, but after SR1, you're not the first to do so.

Basically it's caused by double sided polygons. Try checking Normals_Forward on the materials. If that doesn't help, try adding a noise node as displacement at a very low setting. Like 0.002 or so. Too small to notice, but large enough to "pull the vertices apart" so to speak.

The Poser 4 renderer isn't a raytracer and does't care AT ALL about normals, which is why you won't see it there. 

In short: Firefly dislikes two-sided polygons :)

Thank you TrekkieGrrrl! I must be learning, because I now know what normals are! In my working life I am a psychologist, and the word has a totally different meaning...

There are 3 primitive squares. square, one sided square ,  and high-res square .

Try the single sided or high-res square with your image map .

Be careful in modelling that you dont make two sided polys , its a problem in Poser as you have found .

Oh, you're gonna have a ball with us Poser users....lmao!

There is nothing normal about normal.

Slightly off-topic, but was the creator of Creepy the Clown a psychologist, or a psychiatrist?  I can't remember.

Also, is it bad that I can pull up dozens of his images in my head, but can't even recall his screen-name? It's driving me nuts.

don tatro (creator of creepy) was a clinical psychologist with the arizona state penal system.  it meant that he was very familiar with the sociopathic behaviour that we useta see alot on this site.  but the users here have really mellowed out in the last two or three years. :lol:

you still have time to run......

it's to late for us... we see in poses, wireframes, normals and texturemaps and nodes....

(seriously. I can overlay wireframes over something I'm looking at. I'm Doomed!)
